We Guarantee Sub-MOA accuracy with our Single Edge Land Barrels. We also offer a full lifetime warranty on this barrel, and yes, that includes shooting out the rifling. If you shoot it out, send it back to us and we will replace it, no questions asked. We have reports back from our customers reaching Sub .3" groups. This barrels features a slightly narrower contour reducing weight over our Fluted barrel by 3oz.'s.

Note that with the Nitriding, barrels need about 60 rounds to break in. Recommended break in procedure is to fire 15 rounds at 1 round per second then let the barrel be cool to the touch. Repeat another 3 times for a total of 60 rounds.
